Just did some testing
The full intro is on the [cr CLS] disks, afterwards the Psygnosis, then Reflections, then Awesome screen are shown... You are then asked to insert Disk 2 in DF0 and Disk 3 in DF1. Tried combinations with [cr CLS] disks and all [cr HZ] disks but cannot get past this
All a bit messy really
I think if you boot using the [cr HZ] disks they all boot straight to the Psygnosis, then Reflections, then Awesome screen (no intro). The game actally works afterwards though
We do need a clean crack with full intro
